  1. aIn this table, the respective contribution in percentages of upper gut and hindgut were compared by T-test in each dietary treatment. No superscript indicated that there was a significant difference in the respective contribution in percentages of the upper gut and hindgut each dietary treatment. The superscript “NS” represented that there was no significant difference. The SE represented the standard error of the results of upper gut or hindgut in each experimental treatment
